GA-6RZ2— GENERAL INFORMATION
Excitation System
WARNING:
All GA-series generators use a magnet attached to a flywheel
to produce AC voltage from a lamp coil beneath the flywheel.
As the magnet passes the coil it produces approximately
19-22 AC volts.
Before connecting this generator to
any building’s electrical system, a
licensed electrician must install an
isolation (transfer) switch.
This voltage (19-22 VAC) is then sent to the control box that
contains three rectifying diodes:
Serious injury or death may result
without this transfer switch.

Excitation (diode 1)
Battery (diode 2)
Slow Down (diode 3)
GA-6RZ2 FAMILIARIZATION
Generator
The AC voltage will pass through the excitation diode that
converts the voltage to DC power.
The Multiquip Model GA-6RZ2 generator has been designed
as a portable lightweight power source for 60 Hz (single-
phase) vibrators, lighting facilities, power tools, submersible
pumps and other industrial and construction machinery.
This DC power is then sent to the excitation windings housed
within the main windings commonly called the "stator".
This generator is powered by a ROBIN gasoline engine. The
alternator, a brushless revolving-field type, is permanently
aligned to the engine through rigid coupling.
This voltage is then transferred into the rotor through
induction.The rotor contains two diodes within it which rectify
the DC voltage and send it out through the main windings,
as AC voltage.
The generator is mounted on rubber vibration isolators that
have a steel base backplate which is attached to the
protective steel pipe carrying frame.The protective carrying
frame is made of steel tubing and fully wraps around the
generator to protect against damage.
Engine
The four-cycle air-cooled ROBIN gasoline engine is designed
to meet every performance requirement of this generator.
Reference Table 1, page 8 for engine specifications.
This portable generator is supplied with a electrical control
box. To reduce vibration caused by the engine, the control
box is also placed on rubber isolators.
Figure 1 (page 10) shows the basic controls and indicators
for the GA-6RZ2 generator.
Control Box
The control box has the following: (all outputs are 60 Hz,

generator in a manner so that the exhaust will not be discharged
in the direction of nearby homes.
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
The installation site must be relatively free from moisture and
dust. All electrical equipment should be protected from excessive
moisture.Failure to do will result in deterioration of the insulation
and will result in short circuits and grounding.
Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any gasoline engine
are very poisonous if discharged in a closed room, but
harmless if allowed to mix with the outside air.If the generator
is installed indoors, you must make provisions for venting
the engine exhaust to the outside of the building.
Foreign materials such as dust, sand, lint and abrasive materials
have a tendency to cause excessive wear, not only to the engine
parts, but also to the alternator parts.
CAUTION :
CAUTION :
An electric shock is apt to happen when
vibrators are used. Pay close attention to
handling when operating vibrators and
always use rubber boots and gloves to
insulate the body from a short circuit.
Pay close attention to ventilation when
operating the generator inside confined
areas. The engine exhaust contains
noxious elements.

starting the engine.
Ground
Extension Cable
When electric power is to be provided to various tools or loads at
some distance from the generator, extension cords are normally
used. Cables should be sized to allow for distance in length and
amperage so that the voltage drop between the generator and
point of use (load) is held to a minimum. Use the cable selection
chart (Table 2 ) as a guide for selecting proper cable size.
The nut and ground terminal on the generator should always
be used to connect the generator to a suitable ground. The
ground path should be of #8 size wire.
Connect the terminal of the ground wire between the lock
washer and the nut and tighten the nut fully. Connect their
end of the wire to a suitable ground.

GA-6RZ2— LOAD APPLICATION
Single Phase Load
CAUTION:
Motors and motor-driven equipment draw
much greater current for starting than
during operation.
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generator for operating the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require 130—
150% more wattage than the rating on the nameplate, as
the wattage is influenced by the efficiency, power factor and
starting system of the equipment.
An inadequate size connecting cable which cannot carry
the required load can cause a voltage drop which can burn
out the appliance or tool and overheat the cable.
The idle control is operated at minimum load capacity of
100W. If the load capacity is less than 100W, throw the idle
control switch to the OFF position.
NOTE
If wattage is not given on the equipment's
name plate, approximate wattage may be
determined by multiplying nameplate
voltage by the nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
To determine the running wattage for your load, multiply the
running wattage as indicated by steps 1, 2, and 3 below:
1. INCANDESCENT LOADS
Lights, heaters and similar appliances.
Total the running wattage and multiply by 1.
Example:
29 light bulbs @ 100W each = 2.9 KW
use a 3 KW generator.
2. SMALL MOTORS
Drills and other small power tools.
Total the running wattage and multiply by 2.
Example:
A 1 inch drill runs at 1 KW
use a 2 KW generator.
3. LARGE MOTORS
Submersible pumps, table saws etc.
Total the running wattage and multiply by 3.
Example:
A conveyor belt runs at 8 KW
use a 24 KW generator.

GA-6RZ2— MAINTENANCE
Service Daily
General Inspection
If engine is operating in very dusty and dry grass conditions.
A clogged air cleaner will result in high fuel consumption,
loss of power and excessive carbon buildup in the
combustion chamber.
At least daily or prior to each use, the generating set should
be cleaned and inspected for deficiencies. Check for loose,
missing or damaged nuts, bolts or other fasteners. Also check
for fuel or oil leaks.
Cleaning the Fuel Strainer
Engine Side (Refer to the Engine Instruction Manual)
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
Securely fasten the fuel strainer cap so that fuel will not
leak. Check the fuel strainer every 200 hours of operation or
once a month.
Check Oil Level
Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Make sure the generating set is level.The
oil level must be between the two notches on the dipstick.
Changing Oil
Spark Plug
Change oil after the first 20 hours of operation. Drain and
refill the engine crankcase every 50 operating hours or once
a week thereafter.Drain crankcase oil into a suitable container
while engine is still warm.Replace the drain plug tightly.Add
oil through the filler hole.
Remove carbon build-up on the spark plug (Figure 4) with a
wire brush. Set the spark plug gap to 0.6—0.7mm (0.024-
0.028 inch).Tighten with a spark plug socket wrench. Clean
the spark plug every 50 operating hours or once a week.
Air Cleaner
Every 50 hours: Remove air cleaner element (std. or heavy
duty types), and wash in kerosene or liquid detergent and
hot water. Wrap foam element in a cloth and squeeze dry.
Wipe heavy duty paper element dry with toweling. Saturate
element with kerosene; squeeze excess from foam element.
Wipe excess from heavy duty paper element.
